Sab Hauv Cov Txheej Txheem Tsim Khoom ntawm Flux Cored Wire: Cov Teeb Meem Tseem Ceeb thiab Cov Kev Kho Kom Zoo

Qhov Sawv Ntxov ntawm Flux Core Welding Wire

Nyob rau hauv xyoo tas los no,hlau vuam flux coretau tshwm sim los ua ib qho kev xaiv nyiam thoob plaws hauv kev lag luam xws li kev tsim nkoj, cov qauv hlau, kev khawb av, thiab kev tsim khoom siv hnyav. Nws qhov kev nce sai yog tsav los ntawm qhov kev thov rau kev ua haujlwm zoo, pheej yig, thiab kev daws teeb meem vuam uas hloov tau.

Piv rau cov hlau khov kho lossis cov electrodes ib txwm muaj, cov hlau flux cored muaj cov nqi tso tawm siab dua, zoo dua qhov vuam, thiab ua tau zoo heev hauv txhua qhov chaw vuam. Cov txiaj ntsig no ua rau nws muaj txiaj ntsig tshwj xeeb hauv kev tsim khoom loj uas qhov ceev thiab lub zog tseem ceeb heev.

Cov txiaj ntsig zoo ntawm Flux Core Welding Wire

Qhov kev nyiam ntawmhlau vuam flux coreyog los ntawm ntau qhov txiaj ntsig ntawm kev siv tshuab: 

Kev ua haujlwm vuam zoo: Kev tsim khoom yog txog li 3-5 npaug ntawm cov electrodes ib txwm muaj.

Muaj peev xwm ua tau txhua qhov chaw: Haum rau kev vuam ntsug, kab rov tav, thiab saum taub hau.

Cov kab tawg qis dua thiab cov vuam huv dua: Tshwj xeeb tshaj yog nrog cov xov hlau flux qis, uas txo cov sijhawm ntxuav tom qab vuam.

Cov qauv tsim tau: Lub peev xwm los kho cov khoom xyaw tseem ceeb tso cai rau cov xov hlau tshwj xeeb ua tau raws li cov kev xav tau tshwj xeeb ntawm cov hlau.

Kev siv nyiaj tsim nyog: Tus nqi vuam tag nrho raug txo qis vim yog kev ua haujlwm zoo dua thiab cov khoom pov tseg tsawg dua.

Cov Teeb Meem Tseem Ceeb hauv Kev Tsim Hlau

Txawm hais tias nws muaj txiaj ntsig zoo, kev tsim cov hlau flux cored muaj ntau yam teeb meem kev siv tshuab uas tuaj yeem cuam tshuam rau cov khoom zoo thiab kev sib xws:

Kev faib cov hmoov tsis sib xws: Kev hloov pauv ntawm cov hmoov thaum lub sijhawm dov tuaj yeem ua rau cov ntu hollow lossis cov vuam tsis muaj zog.

Kev ua haujlwm tsis zoo: Kev sau tsis txaus lossis cov xov tsis zoo tuaj yeem ua rau cov hlau vau, xau, lossis tawg.

Qhov tsis zoo ntawm qhov chaw thiab qhov porosity: Feem ntau cuam tshuam nrog kev ua qias tuaj lossis kev tsis sib xws hauv cov khoom xyaw tseem ceeb.

Kev tawg ntau zaus thaum lub sijhawm kos duab: Feem ntau yog vim muaj kev nruj tsis raug, kev ua haujlwm tawv ntau dhau, lossis cov menyuam tsis sib haum.

Cov Tswv Yim Txhim Kho Cov Txheej Txheem

Yuav kom daws tau cov teeb meem no, cov chaw tsim khoom yuav tsum tsom mus rau kev sib xyaw ua ke ntawm kev txhim kho cov khoom siv, kev tswj cov khoom siv, thiab kev tswj cov txheej txheem.

Kev Kho Kom Zoo thiab Kev Teeb tsa Cov Menyuam

Kev teeb tsa cov menyuam dov kom raug yog qhov tseem ceeb kom ntseeg tau tias cov kab sib dhos tseem ncaj thiab kaw zoo. Cov menyuam dov tsis sib dhos yuav ua rau cov kab sib dhos helical lossis ntswj ntau dhau, ua rau hmoov xau lossis xaim deformation. Qhov sib txawv ntawm cov menyuam dov thiab cov txheej txheem nias yuav tsum tau calibrated rau kev txo qis maj mam kom khaws cov xaim kom ruaj khov.

Qhov Zoo thiab Kev Tswj Xyuas Hmoov Core

Cov yam ntxwv ntawm kev ntws ntawm cov hmoov tseem ceeb yog qhov tseem ceeb. Qhov loj me ntawm cov khoom me me, cov duab, thiab kev huv si cuam tshuam rau qhov sib xws ntawm cov khoom sau thiab tus cwj pwm ntawm kev sib xyaw. Cov hmoov me me dhau yuav txo qhov kev ntws, thaum cov khoom me me tuaj yeem ua rau muaj kev sib cais. Rau cov hlau tsis muaj zog ntawm cov hlau tseem ceeb, kev tswj hwm qhov sib npaug ntawm cov hlau yog qhov tseem ceeb kom txo qis kev oxidation thiab txhim kho qhov zoo li vuam.

Kev Ntxuav thiab Kev Kho Mob Ua Ntej ntawm Cov Hlau Strip

Ua ntej tsim, cov hlau yuav tsum tsis muaj roj thiab cov khoom tsis huv. Cov roj seem tuaj yeem raug ntes hauv cov hlau, ua rau muaj roj porosity lossis txawm tias tawg txias thaum vuam. Kev ntxuav ultrasonic yog ib txoj hauv kev zoo heev, siv cov cavitation rog los tshem tawm cov khoom me me thiab xyuas kom meej tias qhov chaw huv.

Kev Tswj Xyuas Qhov Kev Sau Zoo Tshaj Plaws

Qhov kev sau ceev—qhov sib piv ntawm cov hmoov rau tag nrho cov hlau hnyav—yuav tsum tau tswj kom nruj. Qhov kev sau ceev qis ua rau cov hlau tsis muaj puv uas yooj yim tawg, thaum qhov kev sau ceev siab ua rau muaj kev pheej hmoo ntawm kev xau thiab ua rau muaj teeb meem hauv kev kaw lub seam. Kev sib npaug ntawm qhov kev sau ceev yog qhov tseem ceeb kom ntseeg tau tias qhov vuam sib xws thiab kev ua haujlwm ntawm lub tshuab.

Qhov Sib Piv ntawm Cov Hlau Sib Nqus thiab Kev Ua Haujlwm Kho Kom Ruaj Khoov

Kev nias siab thaum lub sijhawm tsim ua rau ua haujlwm tawv, ua rau lub zog tensile nce ntxiv tab sis txo qhov ductility. Qhov no ua rau cov hlau yooj yim tawg rau theem tom qab. Siv cov menyuam tuag es tsis txhob siv cov pwm ruaj khov hauv kev kos duab thaum ntxov pab txo qhov kev ntxhov siab sab hauv thiab khaws cia ductility.

Kev Siv Zog thiab Kev Tswj Ceev

Cov txheej txheem kos duab yuav tsum sib npaug lub zog rub thiab qhov ceev. Lub zog rub ntau dhau los ntawm kev nias siab lossis cov qauv tsis zoo ntawm lub pwm tuaj yeem ua rau cov xov hlau tawg tam sim ntawd. Kev maj mam ua kom nrawm dua - pib ntawm qhov ceev qis - pab txo qhov siab ntawm kev nruj thiab txhawb kev hloov pauv sib xws.

Cov Lus Qhia Txog Kev Siv Tau Zoo & Cov Lus Qhia Txog Kev Vuam

Yuav kom ua tau zoo tshaj plaws hauv daim teb, ntawm no yog qee cov lus qhia siv tau zoo ntawm cov hlau flux core welding:

Rau cov hlau tsis xebhlau flux core, ntxuav cov chaw kom huv si ua ntej thiab siv DCEN (Direct Current Electrode Negative) qhov twg siv tau.

Siv qhov loj me ntawm lub taub hau kom raug kom tsis txhob muaj teeb meem pub mis, tshwj xeeb tshaj yog nrog cov hlau tawv tawv flux cored.

Khaws cov xov hlau rau hauv qhov chaw qhuav, tswj qhov kub thiab txias kom tiv thaiv kev ua qias tuaj ntawm cov dej noo.

Kho qhov voltage thiab cov xov hlau pub rau ntau qhov chaw sib txawv kom tswj tau qhov ruaj khov thiab nkag mus.
